Switch State Control
KEY PROGRAMMING SWITCH STATE CONTROL
Special Tool(s)
NOTE:
- The spare key programming switch is a programmable switch which provides the capability to enable/disable the normal customer spare key programming procedure detailed in the Owner's Literature. It must read ENABLE if more than 2 keys need to be programmed into the instrument cluster (IC). This programmable switch is provided as a convenience for rental company fleets or other fleet purchasers who may not want the spare key programming procedure available to the vehicle driver.
- The spare key programming switch state can be viewed with the IC SPAREKEY PID.
- If the SPAREKEY PID reads ENABLE, up to 8 keys total can be programmed into the IC using Key Programming Using Two Programmed Keys. If the SPAREKEY PID reads DISABLED, the Key Programming Using Two Programmed Keys procedure will not function. This switch is set to ENABLE when the vehicle is built. This PID does not affect the Key Programming Using Diagnostic Equipment or the Spare Key Programming - Unlimited Key Mode procedures.
1. Insert a programmed passive anti-theft system (PATS) key (or integrated keyhead transmitter [IKT]) into the ignition lock cylinder and turn the key from the OFF position to the ON position.
2. From the scan tool, enter TOOLBOX. Select BODY-SECURITY-PATS Functions and follow the on-screen instructions to ENTER SECURITY ACCESS.
3. NOTE: The default setting on delivery of all new vehicles is ENABLED, when viewing the IC SPAREKEY PID.
From the scan tool menu select: CUSTOMER SPARE KEY PROGRAMMING ENABLE and press the tick mark.
- CUSTOMER SPARE KEY PROGRAMMING ENABLE - spare key programming procedure is accessible.
- CUSTOMER SPARE KEY PROGRAMMING DISABLE - spare key programming procedure is not accessible.
